I used to have one generator that required flashing almost every time I used it. I solved that problem by drilling the edge of the face of one stator pole and gluing a tiny super-magnet in the hole. Problem solved for as long as I owned the unit. This is ingenious. There will always be "residual" magnetism in the poles.. Yea, after the power is off. Then, its like a capacitative effect, but it could be dangerous if you take it apart (if it isn't first bled). You know, it could "whack" you a bit. |

Electricity and magnetism behave differently from that under our yellow sun. |

begin to get you thinking straight. Yeah, with that fancy dime-store ammeter wanna-be professor crap. |

Say what ? You saw what I wrote. What, are you blind, Terry? Residual magnetism can act as a capacitor and "bite" you ? I'll get the popcorn , this is gonna be interesting . Well actually Terry, maybe, just maybe it won't. Maybe, if you unplug something and take it apart, maybe nothing'll bite. -- |

You can lead a horse to water but... As was the end to the thread when you said, "Overhead commercial lighting voltage is 277 so its less current and less dangerous," Do you still stand by that statement or have you been enlightened. That ... Has been bothering you? all this time? Mike, I'm not a professional engineer and clearly you aren't either. If I honestly want to know, I could find out from several places. I don't have to know. I just pull wire, install devices & supports and drive trucks. I don't have a journeyman's license in electrical, nor do I want the RESPONSIBILITY of having one. btw, you said, "with that fancy dime-store ammeter" sounds like maybe you bought yourself a new multimeter that you're proud of, go ahead, tell us about it. What did you get? My fluke is burned out. I only use a hot stick when needed. |

Terry, if I want to know what can shock me and what can't, I'm sure I can find out way quicker than you.

The generation of electrical current using a magnet requires the magnetic field interacting with a coil of wire , it has no storage capacity and *CANNOT* "bite" you . Well, you're wrong you know. A magnet can bite you, just get your finger between one of the big rare earth magnets and a steel plate. But of course that's just brute strength, no 'lestrics at all. :-) -- Cheers, John B. |
